No special tricks, really.  My basic setup:
  - Set up domain-0 using raw disk partitions, so I don't have to worry
    about starting LVM from an initrd.
  - Leave a large disk partition unused initially; it will be devoted to
    LVM.
  - Install the lvm2 package from Debian in domain-0.
  - Run pvcreate on the empty large partition, followed by vgcreate.
  - Use the LVM tools in domain-0 to allocate space for the guest
    domains, then export those devices to the guests.  The guests don't
    know the space comes from LVM.

If necessary, I can add more space to domain-0 with LVM as well, but
thus far I've been getting by just fine with the initial partitions for
domain-0, and using LVM solely for space for xenU domains.
